- An optical measurement system composed of an optical microscope (Olympus BX60) and an optical multichannel analyzer (EGG OMA 1460) has been assembled and tested.

The light source, a 100 W halogen lamp, and the diode array detector, result in high sensitivity in the wavelength region of 450-750 nm.
